Le L'Accel 15 Click Board™ est une carte complémentaire compacte qui contient un capteur d'accélération à longue durée de vie. Cette carte est équipée du BMA490L, un capteur d'accélération triaxial numérique 16 bits hautes performances avec une disponibilité étendue jusqu'à dix ans de Bosch Sensortech. Il permet des mesures d'accélération à grande échelle sélectionnables dans des plages de ±2g, ±4g, ±8g et ±16g sur trois axes avec une interface hôte configurable qui prend en charge la communication série I2C et SPI et avec des fonctions d'interruption intelligentes déclenchées par le mouvement sur puce. Le traitement et l'évaluation intelligents du signal dans l'ASIC de l'accéléromètre permettent une reconnaissance gestuelle avancée pour de nombreuses applications IoT industrielles où une faible consommation d'énergie est vitale. Cette Click Board™ convient aux appareils électroménagers, aux outils électriques et à d'autres produits industriels dont la durée de vie est essentielle.
Le clic Accel 15 est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does the Accel 15 Click Board™ Work?
The Accel 15 Click Board™ as its foundation uses the BMA490L, a high-performance 16-bit digital triaxial longevity acceleration sensor with extended availability of up to ten years from Bosch Sensortech. The BMA490L is highly configurable with a programmable acceleration range of ±2/±4/±8/±16g, and intelligent on-chip motion-triggered interrupt features (any/no motion) optimized for industrial applications, routed to the INT and AN pins of the mikroBUS™ socket. In addition to all these features, it also has excellent temperature stability (low-temperature drift), low noise, and low offset.
The sensor features a high-performance measurement mode with low pass filters and current consumption of 150μA in Full-Operation Mode, making it robust to temperature fluctuations with a maximum output data rate of 1.6 kHz. In Low-Power Mode, the current consumption is reduced to 14 µA, meeting the current consumption requirements of Always-On applications.
Accel 15 Click provides the possibility of using both I2C and SPI interfaces with a maximum frequency of 1MHz for I2C and 10MHz for SPI communication. The selection can be made by positioning SMD jumpers labelled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or else the Click board™ may become unresponsive. While the I2C interface is selected, the BMA490L allows the choice of the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled as ADDR SEL.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Accel 15 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on the mikroE GitHub account.
Library Description
This library contains an API for the Accel 15 Click Board™ driver.
Key Functions
accel15_cfg_setup- Config Object Initialization functionaccel15_init- Initialization function.accel15_default_cfg- Click the Default Configuration function.
Example Description
This library contains an API for the Accel 15 Click Board™ driver. The library initializes and defines the I2C or SPI bus drivers to write and read data from registers. The library also includes a function for reading X-axis, Y-axis, and Z-axis data.
The application is composed of three sections :
void application_task ( void ) {
if ( accel15_get_int_1( &accel15 ) == ACCEL15_DRDY ) {
accel15_get_axis_data( &accel15, &axis );
log_printf( &logger, "tX : %5d rn", axis.x );
log_printf( &logger, "tY : %5d rn", axis.y );
log_printf( &logger, "tZ : %5d rn", axis.z );
log_printf( &logger, "-------------------------rn" );
Delay_ms( 1000 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE GitHub account.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Accel15
Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
mikroSDK
the Accel 15 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
